We didn't have these supply shocks, but now we are witnessing it firsthand." Since the transport sector accounts for up to 75 per cent of the country's liquid fuel demand, experts suggest that significant solutions for reducing oil dependence could arise from changes in this sector.Electric vehicles (EVs) are widely seen as a practical way for Australia to reduce its reliance on imported oil.Dia said that this could be a "medium to long-term" solution for Australia."The most straightforward way to actually reduce our reliance on imported oil is to look at vehicle electrification," he explained."By turning to electrification, we can reduce our reliance on that imported oil or even on oil altogether The technology, infrastructure, supply chains, and networks exist."However, some warn that the production of biofuels can still depend on fossil fuels, potentially limiting their benefits.Dodson said that "most agricultural production in Australia is heavily dependent on fossil fuels.""So yes, we can produce biofuels that then may be used in motor vehicles, but in order to produce those fuels, we've probably used almost as much diesel or petrol, more likely diesel, to actually produce the agricultural products that can then be turned into oil."It's actually difficult to get a big gain in additional energy by the time it makes its way into the car."At scale, it's not really going to solve many of our challenges and problems."Beyond alternative fuels, experts say reducing oil dependence will also require changes to how Australians move around their cities and to the public transport system as a whole.With the current fuel shortage, Victoria and Tasmania have offered free public transport for a limited time to encourage people to use their cars less
